Programmable Oscillators

Oscillators are electrical circuits which have the ability to generate a continuous output signal with a specified frequency. Most oscillators are designed to produce a sine or square wave output. Programmable oscillators offer the flexibility to be configured to operate over a wide range of frequencies with the required accuracy and stability. A programmable oscillator can be programmed multiple times to generate different frequencies. Because of their versatility and precision, programmable oscillators are widely used in communication systems, digital signal processing, frequency synthesis and other applications. In this article, we will discuss the application field and working principle of SIT8008ACA8-XXS programmable oscillator.
